Model meaning
Installation and user guide
◇ This product should be installed on circuits of systems and equipment with a rated voltage matching that of the surge arrester.
◇ Before installation and use, check the tightness of the connection between the surge arrester element and the drop-outmechanism to ensure good contact and smooth operation.
◇ Adjustment method: Rotate the copper contact (with pull ring) on the surge arrester so that the opening force is within 6–10 kg, ensuring the pull ring side of the copper contact faces outwards. Then tighten the lower nut to prevent the pull ring from rotating.
◇ During installation, the surge arrester should be positioned at an angle of 15–30 degrees to the plumb line, with a minimum distance of 200 mm.
